Fertilization and Irrigation - Theory and Best Practices
Fertilization and irrigation are among the most important drivers of yield, quality, and profit in crop production.
This is not a book to read once and put away. It is a reference used when planning fertilizer programs, interpreting soil and water tests, and adjusting irrigation and fertigation decisions during the season.
Written for agronomists, students, farmers, and growers working across most field, greenhouse, and orchard crops who want to replace guessing with a clear, structured approach to fertilization and irrigation decisions.
Trusted by more than 15,000 agronomists and growers worldwide.
Why This Book Matters
Fertilization and irrigation are often managed with partial information or simplified assumptions. Small errors in nutrient planning, water quality interpretation, or irrigation timing accumulate into significant yield and quality losses.
This book provides the agronomic principles needed to design reliable, consistent, and efficient nutrient and water programs across all production systems.
What You’ll Learn
Across 260 pages, the book builds a structured understanding of crop nutrition and irrigation management, from soil and water fundamentals to practical fertigation and nutrient solution design.
Clear, Practical Guidance
Each concept is explained in a straightforward manner, supported by examples that can be applied directly in the field, greenhouse, or hydroponic environment.
